Is Xbox series s better with HDMI 1.4 monitor or HDMI 2.0 monitor and how different in...

The Xbox One S will run at 4K if the monitor does 4K@60Hz. When connected via HDMI, the HDMI port on the monitor must be at least version 2.0.

According to the product sheet, you should be able to get 4K@60Hz if you connect the Xbox to the HDMI 2.0 port on the monitor.

The other two HDMI ports, "HDMI 1.4" and "HDMI 1.4(MHL)" will not support 4K@60Hz, and the Xbox will likely default to 1080p.

Make sure also that the monitor supports, HDMI Displayport 2.0 as that what the Xbox One S and Xbox One X use, I believe that the standard Xbox One only uses HDMI Displayport 1.4,

Its possible that the monitor only supports HDMI Displayport 1.4,

Its possible that you're TV has HDMI Displayport 2.0, which could be the reason it works on the TV but not the monitor.

It's nothing to do with your console...it is a limitation with your monitor.

Your monitor comes with 2 HDMI 1.4 ports (not 2.0)....120Hz and 144Hz are only supported via DP on this monitor, so this would be why it is defaulting back to 60Hz every time

Here's a forum thread on Linus Tech Tips about it (albeit with the better Series X but it's the same thing):

Edit: Have edited the thread to provide more clarity regarding HDMI 1.4

Mini-HDMI is just the regular HDMI pinout in smaller form factor. Strange that your monitor uses mini-HDMI, but you don't need a special adapter. You would just need to get an HDMI-to-mini HDMI cable. For a monitor of that caliber (and price), it had better
at least come with one of these cables!

You also mentioned it's HDMI is version 2.0. HDMI 2.0 is the required version for the Xbox One S/X to output 4K@60Hz with HDR, so it
should display without a problem. The things you read about some monitors only supporting up to 4K@30Hz is because their HDMI ports are version 1.4.

Both should support 1080p @ 120hz but your monitor or TV must also support it. Given that Series S has a lot of features like HDR10 etc. I would prefer to use the HDMI 2.0 since it supports up to 18Gbps whereas 1.4 is only up to 10.2Gbps.
